What could cause the roof of my mouth to be swollen?

There are two reasons, one could be normally drinking hot tea or coffee, specially this occurs
when you suddenly drink hot as immediate it is poured in a cup, next is drinking dry wine without
ice or water, and also the natural body heat when becomes excess it can cause.

I had the same problem with my roof too. In my case it was the snow that stayed longer on the roof and made it wet. But it can also be the rain or the sun if the roof is made of some material that can melt.

A while back, I was having some pain with a tooth and went to the dentist. He ran his finger across the top of my mouth and said there was some swelling. I had the beginning of an infection from the decaying tooth. I was given an antibiotic for infection.

the roof of your mouth could swell for several different reasons. maybe you're having an allergic reaction to something that you ate or took orally. Have you tried anything new lately that could cause this? Could be also that you ate something that unknowingly irritated your roof. give 2days
